Application filed May 5,

My invention relatesto devices for placing and withdrawing electriclight bulbs a and to turn the bulb. i

A further purpose isto frictionally engage the bulb by the clampingjaws.

Further urposes will appear in the specification an in the claims. e Ihave preferred to illustrate my invention by one general form only,selecting a form which is simple, practical and inexpensive and which atthe same time well illustrates the principles of my invention.

Figures 1 and 2 are side elevations, taken at right angles to eachother, showing the preferred form of my invention with a lamp ulboutlined within the clamp. V Figure 3 is an end elevation of thestructure of Figure 1, omitting the bulb.

Figure 4 is afragmentary section of Figure 1 upon line 44, and toenlarged scale.

Figure 5 is a perspective view showing the clamp holding a short bulb.

lVhere ceilings are high and in other places where lamp sockets aredifficult of 7 access, a holder or clamp mounted upon a handle or polemust be used to place and withdrawthe lamps. My device is intended forthis use and is shown as applied to a lamp bulb, 6 adapted to be fittedinto or withdrawn from the socket 7.

My holder Scomprises primarily clampingjaws 9 and 10 and a flaringfrictional engaging portion intended to be pressed against the end ofthe bulb so as to make it possible to turn the bulb within the socket.The frictional flare and the clamp arealranged simply and convenientlyby mounting the frictional surface within a flaring member 11 mountedupon a pole 12 by means of a socket 13. I show a simple and inexpensivemeans for fastening the clamping members and the friction members to theflaring-device, here shown as a funnel 1926; Serial No. 108,828.

by attaching the clamps to the flaring member at 14, 15, 16 and-l'T-andextending the ends downwardly into the flaring member, 1. e.converging.them toward the bottom of the fi'ari'rig1nember. so as tomount upon them cushions or friction devices 18 for which, rubber,tubing may conveniently be used. The wires carryingthe' rubber or thetubin'gmay engagesome portion of the (ill interiorof the flared body orsocket to sns tain them from swinging movement when the clamp wiresaresprung away from each other to engage a bulb, withjthe result thatthe clamps spring about their points of attachment at 14, 15, 16 and 17'to grip the bulb and prevent it from falling out. i need not use thespring clamps to grip the bulb with suflicient pressure to prevent theturning of the bulb Whether the clamping portions 19 and 20 of the wiresbe covered with frictional material as at 21 in Figure 5 or not as inthe other figures. Ordinarily my invention can be practiced to better advantage by using thefrictional engaging surfaces 18 of the rubber tubingto engage the end of the bulb, giving friction when pressure is exertedagainst the bulb lengthwise and 1 little friction otherwise. Both can beused.

In Figure 5 a rubber band 22 is mounted upon the clamping wires toafford frictional engagement-at 22 with a short bulb 6. Where this is tobe used the band can be restricted easily to the. part of the/clampingwires where it will be most useful by forming bends or kinks 523 in thewire to hold the band.

In operation the bulb is pressed longitudinally against the ends 19, 20of the spring clamps, separating them and allowing the bulb to enter tothe position shown in Figures 1, 2' and or Figure 5 where the inner partof the bulb is held. and centered by the spring clamps and the outerrounded end of the bulb rests against the rubber tubing 18 or band 22,frictionally engaging it and permitting the bulb to be screwed intoplace in its socket. Withdrawn from about the bulb by longitudinalmovement of the holder. For withdrawal the clamps are sprung to placeover the bulb by longitudinal pressure upon the holder and the bulb iswithdrawn by screwing it out of the socket. It can subsequently bedetached from the bulb.

In view of my invention and disclosure The spring clamps can then be illvariations and modifications to meet individual whim or particular needwill doubtless become evident to others skilled in the art, to obtainpart or all of the benefits of my invention without copying thestructure shown, and I, therefore, claim all such in so far as they fallwithin the reasonable spirit and scope of my invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a device for placing and removingelectric light bulbs, a flared shell, spring wires secured to the shelland located along the inside of the shell and extended without the sameto form a spring clamp outside of the shell, cushioning means for thebulbs mounted directly upon the spring wires, and supports thereforwithin the shell.

2. In a device for placing and removing electric light bulbs, a flaredshell, spring wires secured to the shell and converged along the insideof the shell and extended without the same to form a spring clampoutside of the shell and supports therefor adapted to engage the end ofthe bulb.

3. In a device for placing and removing ,electric light bulbs, a flaredshell, adapted for mounting upon the end of the bulb, in combinationwith spring wire side clamps for the bulb mounted upon the shell andreversely extended inside the shell and friction members mounted uponthe inside of the extensions to engage the end of the bulb.

4-. In a device for placing and removing electric light bulbs. a funnelhaving :1 seat at the rear for a handle, spring wires attached to theflare of the funnel. to engage the side of the bulb outside of thetunnel and rearwardly extending inside of: the fun nel and rubbertubesupon the extensions inside adapted to engage with the end of thebulb.
